Seems to me most of the fuss is over the "gee, I just bought a muzzleloader at Bass Pro Shop for $69.00, is it a good gun?" type. You get what you pay for. I've hunted with and shot with flint and percussion tradtional muzzleloaders for over thirty years without any issues. Made some minor mistakes over the years, but never any safety proiblems. You CAN blow a traditional muzzleloader with BP, but it takes a lot of work. To do it, you would either have to be the must unlucky person in the world, or the stupidest.

I don't shoot inlines, not because of safety issues, they just are not my area of interest. If you DO shoot inlines, instead of asking Joe Anyone on the 'net, they hide information about your rifle in a thing called "Instructions", or "Instruction Book". If you don't do your homework, and don't do your research, well, stuff happens.
